48 MHz Cortex-M23 with 128 KB flash — memory and peripheral fit for a control node
The R7FA2L1A92DFM#AA0 is a Renesas RA2L1-series microcontroller built around the ARM Cortex-M23 core running at 48 MHz. The industrial temperature grade (-40 to 85 °C) suits it for factory-floor sensor nodes, outdoor enclosure controllers, and under-hood auxiliary modules.
Peripheral set — capacitive touch, CAN, and hardware security
The peripheral list includes a capacitive-touch sensing unit, a CAN 2.0 interface, multiple SCI/UART and SPI/I²C serial channels, a 12-bit SAR ADC with 13 channels, and a single 12-bit DAC. The AES accelerator and true random number generator (TRNG) provide hardware-backed encryption without loading the CPU. With 53 general-purpose I/O lines in the 64-LQFP package, this part can drive a local keypad-and-display HMI while still handling CAN communication and analog sensor acquisition. The 64-LFQFP (10x10 mm) footprint is a common, rework-friendly package — standard hot-air rework profiles apply.
Active lifecycle — no end-of-life pressure for new designs
Renesas lists the R7FA2L1A92DFM#AA0 as an active product. There is no last-time-buy notice, no NRND flag, and no official successor announced. The part is ROHS3 compliant.
